摘　　要：文章针对光伏跟踪支架扭转固有频率计算结果准确度不高的问题,提出了一种考虑了檩条锚固柔性给跟踪支架整体扭转频率带来影响的分析方法,并通过试验对仿真结果进行了验证。其次,对某电站跟踪支架进行了结构改造,提升了其扭转固有频率,并通过现场测试再次验证了分析方法的准确性。Aiming at the problem that the accuracy of the calculation results of the torsion natural frequency of the photovoltaic tracking bracket is not high,an analysis method is proposed in this paper.The influence by the anchorage flexibility of the purlin on the overall torsion frequency of the tracking bracket is taken into account and the simulation results are verified by experiments.And then,the structural rebuilding of the tracking support in the power station is performed to improve its torsion natural frequency while the accuracy of the analysis method is verified by the field testoncemore.
